5. Comparison between HFSQL and CEDB
Previous pageTable of contentsNext page
To display information coming from a database in a window, the controls of this window must be linked to the different database items.
The method for displaying and retrieving information depends on the database used (HFSQL or CEDB).
File link between a window and a HFSQL database
In most cases, the link between a control and an item is defined in the window editor when describing the control ("File" tab). This link allows you to specify the file item that will be used by ScreenToFile and FileToScreen.
File link between a window and a Pocket PC database (CEDB)
This link must be defined by programming (cdbXXX functions).
Other differences
The use of HFSQL databases (Classic or Client/Server) allows you to access the following features (non-exhaustive list):
  • Speed of the HFSQL database.
  • Queries on the HFSQL databases (created with the query editor supplied with the product).
  • Fast application development via Full Application RAD.
  • Features specific to the HFSQL database (encryption, ...)
